While there has been no confirmation from the couple, fans are convinced Bey and Jay have become parents again after girl and boy balloons were spotted being delivered to the LA Medical Centre, where Beyoncé is thought to be giving birth.

Husband Jay Z also missed the Songwriters Hall Of Fame Awards in New York last week, leading people to believe he was busy with his wife.

From the singer's pregnancy announcement to her due date, here's everything we know...

Beyoncé reveals the sex of her twins?

Fans are convinced Beyoné is expecting twin boys after she used her earrings to send a message.

Another added: "*IVF clinic phones ringing off the hook with requests for twins* 'Ma'am, IVF can't give you 'Beyoncé twins'."

To add fuel to the fire, The New York Times reported recently that over 40 per cent of IVF deliveries in America are twins, triplets and higher.

Beyoncé has also spoken previously about the tragic miscarriage she suffered two years before welcoming her daughter, Blue Ivy, who people speculated at the time was carried by a surrogate and that Beyoncé had faked her pregnancy.

Beyoncé baby names

Thousands of predictions of baby names have started rolling in since the announcement.

But betting agency William Hill reminded everyone that nobody correctly predicted the name Blue Ivy.

William Hill spokesman Rupert Adams said: "Nobody managed to correctly predict 'Blue Ivy' and we fully expect that that failure will continue. But here are our best predictions and my money is on Tic & Tac."

A few of our favourite predictions include Kim and Kanye, Adam and Eve, King and Queen and Chilli and Pepper.

Other ridiculous suggestions included Romulus and Remus, Batman and Robin and Pride and Prejudice.

We imagine Beyoncé and Jay Z will pick something far more beautiful!
